Quasars in a Neutral Universe: Chronicling the History of Reionization, Enrichment, and Black Hole Growth

Project description

A new window on one of the most enigmatic periods in our Universe's history

Just as our Earthly history is defined by epochs or ages, so is our Universe’s history. The Big Bang was an extremely rapid expansion of a highly dense point mass, yielding a very hot soup of particles. As the Universe expanded and cooled, protons and neutrons combined, and eventually attracted electrons, forming neutral atoms. This era in which clouds of hydrogen gas blocked light transmission is known as the 'cosmic dark ages'. During the epoch of reionisation that followed, the mysterious star- and galaxy-forming epoch, the intergalactic medium was once again ionised; the first luminous sources appeared, as did enormous black holes, consuming anything within their reach. The EU-funded QuasarChronicles project plans to characterise this intriguing and mysterious reionisation period for a unique window on the history of our Universe.
